Question

Pls help , my geometry teacher can't teach

Answer 1

58 m

Explanation:

The correct answer is 58.

To get the perimeter you add all the sides of the image, however, you are missing 2 values from the image.

If you make the shape into a square where all opposite sides are the same length, then you will see that one missing length is 6 m =(10m-4m).

The other missing number is 12 m which is base of 19 m - 7m that you are given on the top.

So you add the measurements (going clockwise starting at the top, 7+6+12+4+19+10=58 m

Answer 2

58 m

Explanation:

You want the perimeter of the L-shaped figure shown.

Perimeter

The perimeter is the sum of the side lengths. Here, a couple of lengths are missing from the diagram, but that doesn't prevent us finding the perimeter.

Horizontal

The horizontal lengths at the top have the same total length as the length at the bottom marked 19 m. This means the sum of all of the horizontal lengths is ...

2 × 19 m = 38 m

Vertical

The vertical lengths at the right side have the same total length as the vertical length at the left side, marked 10 m. This means the sum of all of the vertical lengths is ...

2 × 10 m = 20 m

Total

The perimeter is the sum of the horizontal and vertical lengths:

P = 38 m + 20 m = 58 m

The perimeter of the figure is 58 m.
